Title: Improvements in controlling electric instruments or apparatus by means of vacuum tubes
IPC: H03F3/32
Filed: 1920-01-29
Abstract: 165,888. Brydon, S. Jan. 29, 1920. Thermionic valves, arrangements nad connections of.-Thermionic valves are used to control the current in a pair of circuits so that, as the current in one circuit increases, that in the other decreases, and vice versa, the operation of the valves being controlled by another current such as that due to the receipt of wireless signals. The udjustment is such that normally a current flows in one circuit and no current or an ineffective current flows in the other circuit, the state of affairs being reversed by the receipt of a signal. The arrangement is described as applied to the marking and spacing coils of a. Morse inker, but is applicable to controlling relays, switches or other instruments or devices operated in like manner by two currents alternately effective. In one arrangement the two control valves are connected in cascade, the anode circuit of the first valve including a resistance and the spacing-coil of the inker, the anode circuit of the second valve including the marking-coil. The grid of the second valve is connected to the anode end of the resistance. The signal currents, after amplification, are led to the grid circuit of the first valve. In a modification, the resistance is replaced by a transformer coupling between the anode circuit, of the first valve and the grid circuit of the second, the latter circuit including a potentiometer for adjustment purposes. As shown in Fig. 2, the signal currents are amplified by a valve C, the anode circuit of which includes a resistance 3. The grid of one control valve A and the filament of the other control valve B are connected to one end of the resistance 3, the other end being connected to the other filament and grid. The spacing-coil S and marking-coil M are included in the anode circuits of the valves A, B respectively. A modification is also described in which the two valves A, B are replaced by a single tube having two anodes and grids and a single filament, the grids being connected to opposite ends of resistance 3 and the filament to an intermediate point. Reference has been directed by the Comptroller to Specification 146,354.

Abstract: 1524572 Radio navigation STANDARD TELEPHONES & CABLES Ltd 29 Jan 1975 03507/76 Heading H4D A receiver for a radio navigation system as described in Specification 1,524,571 and 1,524,573, includes means for allowing detection of the finite spectral width of the received scanned beam signal, since the beam has a finite width in space and therefore produces Doppler sidebands due to the rotation of the aerial aperture. The receiver comprises RF/IF stages, which may be followed by a reference frequency generation circuit (not shown) as described in Specification 1,524,572. Detector D 1 produces an output signal (Fig. 4a, not shown) which is the sub-carrier signal having a time varying amplitude: where # is the beam dwell time. This first detected signal is applied to filter F. The filter characteristics is chosen to have a centre frequency f 0 , the offset frequency, and amplitude tapers the spectrum of the beat signal due to the aerial Doppler components from zero to - 7 dB at the bandwidth limit of Œ 2À5 kHz. The filter output is applied to the second detector D2 whose output is an exact representation of the beam power; e.g. envelope detection. The timing of the beam centre is performed at stage BT. A time reference signal TR is supplied to measure the spatial position of the scanning beam and hence the receiver position.
